Fair point. I used to spend a lot of time on thinking about custom workout routines, measuring my progress, adjusting my workout plan etc., until I realized, you don't really need all that if your goal is to just stay healthy. For that you only need consistency. My app is simple because all you have to do is press "start". I found it difficult to put all that into one tagline. But thanks for your feedback, I will keep thinking about it...
Here's the thing, these apps are everywhere. The problem is people come up with excuses why they can't use them "I'm not near gym equipment", "I don't have time", etc.
Tagline suggestion "Rock hard core in 20 minutes. All you need is a smartphone, a mat, and a chair. It's free!"
Subtext - "Stop paying for costly $100/month gym memberships or expensive fitness equipment. Get the body you want, when you want, and in the comfort of your own house. Upgrade to a Pro account and unlock 3x times the exercises."
Subtext 2 (the upsell) - "Pro memberships are 2x more likely to see the results they want. Upgrade now (click)"
"Just press start" or "Only one button between you and your workout" or "One button to a better you" (okay, not that one). I'm not any good at this, but I like the idea behind your app and I understand what you're trying to say. Quaffapint puts the tagline problem well.
